On reality?

Need to get real and start finding my own stuff to do and prove to myself that i can come up with non trivial math….. someday, i will do pure mathematics ruthlessly And yes…… apart from Math, i would love to meet Tori black….

Berlinale

watched barzakh and the bengali detective at Berlinale Other things, spent a weekend at saint Malo-the beautiful town on the Northern coast of France and realized working on proofs full time can make times when the mind is not required to think more pleasurable than any other feeling can offer

On KPN

The Kahn Principle states that each node in an asynchronous deterministic network computes a continuous function from input histories to output histories, and the behavior of the net- work can be characterized as a least fixed point. Fairness plays a vital but implicit role: the Kahn Principle is only sound when network execution is assumed to be (weakly) fair. Kahn’s model does not extend easily...

Force directed placement

An attempt is made to place cells in their ideal locations by using a mechanical analogy. Two cells separated by a distance D and connected by a net of length L are said to have a force D x L acting upon them. The averaged sum of all such forces on a single cell yields the zero-force target location of the cell.The net weights are treated like spring constants, and the net lengths are treated like...

dht

there are two primary problems with the DHT approach: Most DHTs will require a second locking layer to achieve correctness when implementing a more complex data structure on top of the DHT semantics. In particular, this will certainly apply to eventually-consistent systems in the Dynamo mold. Advanced functionality like range queries needs to be supported natively to be at all efficient.

A randomized graph puzzle

From Geomblog Given an undirected graph G with (possibly different) probabilities on edges, consider the usual random process where we pick each edge independently, but with probability p_e (this is the difference from the standard erdos-renyi model). What is the probability that the resulting graph is connected ?

DETS and mnesia

DETS uses a buddy system to maintain the freelist, and this freelist grows as the data becomes fragmented. The freelist is held in RAM, so this has a negative effect on memory consumption that gets worse over time. In addition, when you close a dets table, this potentially huge data structure needs to be serialized to disc, which can take a while. The only ways of shrinking the freelist is to...

CCC

As i sat at the Bcc in Berlin during the Chaos Congress talking to a friend, it dawned upon me that this part of the world will never have an event like that. Maybe its the coldness, the depression or just the fact that things are just too warm here. The Congress was total fun. The quality of the talks was amazing; a great GO lounge; an even better music lounge and amazing hackers. What more...
